Moscow made a new attempt to dodge a $4-billion lawsuit from Tehran over a failed deal to supply S-300 missile systems by offering another type of air defense system to Iran, Kommersant daily said Saturday.

The new offer on the table is Antei-2500, aka S-300VM, or SA-23 Gladiator in NATO nomenclature, the newspaper said, citing unnamed sources in the Russian arms trade industry. The missile defense system can simultaneously destroy up to 24 aircraft within the range a range of 200 kilometers or intercept up to 16 ballistic missiles.

The deal can be formalized during the visit of outgoing Iranian President Mahmoud Ahmadinejad to Moscow on July 1, an unnamed Iranian diplomat told Kommersant.

Iran was initially interested in the S-300 missile complexes, signing in 2007 a contract worth $800 million for five missile defense systems of this make.

But the deal was scrapped in 2010 by then-Russian President Dmitry Medvedev, who was unilaterally expanding on sanctions against Iran imposed by the UN Security Council.

Iran filed a $4-billion lawsuit against Russia in the international arbitration court in Geneva, which is currently pending review.

Moscow has struggled to have the lawsuit dropped, including by offering the Tor anti-aircraft systems as replacement, media reported earlier this month, adding that the offer was rejected by Tehran.

The Antei-2500, however, may be a better solution. The system does not formally fall under the existing sanctions against Iran while still being useful for the Middle Eastern country, which wants to have protection against a possible missile strike by its enemy Israel, Kommersant said.

While the S-300 was developed for the use by missile defense forces, the Antei-2500 was specifically tailored for the needs of ground forces, which could also be an advantage for Iran, known for its large land force.
